NEW ALARMS SOUNDS OFF IN THE CAB • National Windscreens has launched an alarm system which is triggered by an ultrasonic sensor and activated from outside the vehicle by radio signals from a transmitter the size of a key fob.
An ultrasonic volumetric sensor, mounted on the dashboard or rear parcel shelf, fills the vehicle with an invisible web of ultrasonic waves.
When the pattern of this web of sound waves is disturbed, by a door opening, by a window being smashed or even by a hand reaching in through an open window, the sensor sets off a 115-decibel siren and flashes the vehicle's road lamps.
Each remote-control transmitter has its own unique code so no other remote control can activate or deactivate the alarm. To activate it the driver simply locks the vehicle in the normal way, then presses the transmit button on the remote control device attached to the key ring.
Once activated the system can be disarmed only by the remote control, and even then the signal must be received before attempting to gain entry to the vehicle. There are no keys or concealed switches by which a thief can deactivate the alarm. The system costs £99.60, including installation and VAT; phone (0827) 52925 for more information.
